LEVI D. NORTON, OF CINCINNATI, OHIO ASSIGNOR TO THE E. D. ALBRO COMPANY,OF SAME PLACE. V

GILUIN/G-MACH'INE.

SPECIFICATION forming part of Letters Patent No. 290,094, dated December11, 1883. Application filed August 24, 1883. (No model.)

may be used advantageously in various kinds of cabinet-work,pattern-making, &c., and

for the application of paste, paint, or other viscid or semi-liquidsubstances.

In the accompanying drawings, Figure 1 I 5 is a side elevation ofamachine embodying my invention. Fig. 2 is a transverse section. ofgluing-cylinder and its accessories. Fig. 3 is a partly front and partlyrear elevation of the machine. Fig. 4 is-an elevation of the gearing.Figs. 5 and 6 are detached views of the glue-regulating andglue-distributing de vices, respectively.

Supported at convenient height on a frame,

A, are the bearings B of a horizontal shaft, 0,

2 5 to which is keyed the transferring drum or cylinder D. The peripheryof this cylinder is scored by numerous intersecting grooves or channels,E, for the purpose of enabling said.

cylinder in rotating to collect and carry up a 0 sufficient quantity ofglue. Thetransfer-cylinder'D is partially immersed in a fount,reservoir, or kettle, F, (preferably'of the repre sentedsemi-cylindrical shape,) for containing the heated glue solution. Thefount F has a 3 5 jacket,"G, which is charged with steam or hot waterthrough a,pipe, H. l

A slotted standard, J, serves to guide to a vertical path thejournal-bearings 'K of a pressure-roller, L, to which any desired down-0 ward stress is imparted by an adjustable spring, M, whose force iscontrolled by nuts N upon screw-threaded bolts 0, which extend upwardfrom the guide.

A bracket, P, upon the standard J, sup- 5 ports a scraper, Q, that isattached to said standard by athumb-screw, R, which permits I thescraper to be adj usted to any desired proximity to the periphery of thetransfer-cylinder for efficient removal of superabundant 5o glue.

A vertically-adjustable bracket, T, carries a brush, U, whose bristles,extending upward, as shown in Fig. l and the left half of Fig. 3,operate to distribute the glue uniformly over the surface of the work.

J ournaled in vertically-adjustable and yielding frame V, so as to belocated at a suitable I elevation from the brush U, is a secondpressureroller, WV.

A driving-pulley, X, having suitable connection Y, with the motivepower, is so connected, by gearing I and belting Z, with the cylinder Dand the pressure-roller L, respectively, as to rotate these two membersat the same peripheral velocity in the direction in- 6 dicated by thearrows. The fount F is furnished near its top with an overflow, 3, andat bottom with a discharge-faucet, 4.

A piece to be glued being fed in, as shown at 2 in Fig. 1, is carriedforward by the joint action of the cylinder D and the pressureroller L,and, by its contact with the'periphery of said cylinder, becomes coatedwith glue on its under surface, which glue, on the further progress ofthe stuff through the machine, 7 becomes evenly distributed by the brushU.

The channels E, formed in the periphery of cylinder D,enable it'to takeup from the fount abundant charges of glue, of which, before contactwith the work, allsurplusage is removed by the action of the scraper Q.

For some purposes there may be used, instead of the brush G,adistributing device composed of rubber, of sponge, of leather, of felt,or other suitable material, according to the work proposed to beaccomplished. A bar may take the place of the roller W.

I claim as new and of my invention The combination, in a glue-applyingmachine, of the jacketed fount or kettle F, the 0 channeledtransfer-cylinder D, the pressurerollers L and W, the scraper Q, and thedistributing device U, substantially as set forth. In testimony of whichinvention I hereunto set my hand.
